Chris Douglas commented on MAPREDUCE-1623:
------------------------------------------
bq. Not really. All the classes in jobhistory package are not public, for
example: JobHistory.java. I think this package should be private and the
necessary client side functionality should be available to public from
org.apache.hadoop.mapreduce package (does this need a separate jira?).
If users want to write tools processing the job history, couldn't they use the
classes in this package?

> There are lots of implementation classes in org.apache.hadoop.mapred which
> makes it difficult to see the user-level MapReduce API classes in the
> Javadoc. (See
> http://hadoop.apache.org/common/docs/r0.20.2/api/org/apache/hadoop/mapred/package-summary.html
> for example.) By marking these implementation classes with the
> InterfaceAudience.Private annotation we can exclude them from user Javadoc
> (using HADOOP-6658).
> Later work will move the implementation classes into o.a.h.mapreduce.server
> and related packages (see MAPREDUCE-561), but applying the annotations is a
> good first step.
